Specific embodiment
To facilitate the understanding of the present invention, a more comprehensive description of the invention is given in the following sections with reference to the relevant attached drawings.In attached drawing
Give preferred embodiment of the invention.But the invention can be realized in many different forms, however it is not limited to herein
Described embodiment.On the contrary, purpose of providing these embodiments is keeps the understanding to the disclosure more saturating
It is thorough comprehensive.
It should be noted that it can directly on the other element when element is referred to as " being fixed on " another element
Or there may also be elements placed in the middle.When an element is considered as " connection " another element, it, which can be, is directly connected to
To another element or it may be simultaneously present centering elements.Term as used herein " vertical ", " horizontal ", " left side ",
" right side ", "upper", "lower" and similar statement are for illustrative purposes only.
Unless otherwise defined, all technical and scientific terms used herein and belong to technical field of the invention
The normally understood meaning of technical staff is identical.Term as used herein in the specification of the present invention is intended merely to description tool
The purpose of the embodiment of body, it is not intended that in the limitation present invention.Term " and or " used herein includes one or more phases
Any and all combinations of the listed item of pass.
In the following, being described further in conjunction with attached drawing and specific embodiment to the present invention:
As shown in Figure 1, 2, a kind of cutting tool of hollow mold insert sticking to mould, including cutter hub 20；
The cutter hub 20 is cylindrical body, wherein an end face is provided with cutting edge 50, other end is provided with knife handle 10, intermediate
It is provided with the inner hole 60 coaxial with cutter hub 20；The inner hole 60 is used to avoid the boss of mold.According to the size of hollow mold insert 90,
The outer diameter and inner hole 60 of cutter hub 20 can be adjusted correspondingly in tool sharpening.
As shown in Figure 1, being evenly distributed on centered on the central axes of cutter hub 20 same there are five the total settings of the cutting edge 50
On one datum level X；
As shown in figure 4, the cutting edge 50 edged surface 51 before the equidirectional side direction of rotation T is provided with, in rotation side
The side of T opposite direction is provided with cutting edge inclination face 52；The adjacent cutting sword 50 in the cutting edge inclination face 52 and direction of rotation T opposite direction
Preceding edged surface 51 between connected by rear corner surface 53；In this embodiment, the direction of rotation T of cutting is dextrorotation.
As shown in Figure 1,5, the outer surface of the cutter hub 20 is provided with external chip discharging slot 40 identical with 50 quantity of cutting edge；
The external chip discharging slot 40 is starting point with rear corner surface 53, is extended towards 10 one end of knife handle；What external chip discharging slot 40 was used to cut
Cutting zone is discharged in clast.
Further, as shown in Figure 1,5, the chip-removal hole 30 being connected to inner hole 60, chip-removal hole are provided on external chip discharging slot 40
30 for the clast in inner hole 60 to be discharged.
Further, as shown in figure 4, the angle c of preceding edged surface 51 and datum level X are 82-85 degree.Angle c is smaller more advantageous
In cutting, but lesser angle c is unfavorable to the stability of cutting, and cutter is be easy to cause to shake, and reduces cutter life.
Further, as shown in figure 4, the angle a of cutting edge inclination face 52 and datum level X are 4-6 degree.Suitable angle a can be with
So that cutting edge is kept higher-strength, while there is good cutting stability.
Further, as shown in figure 4, the angle b of rear corner surface 53 and datum level X are 9-12 degree.Suitable angle b can be
Good clast accommodation space is provided in cutting process, while there is preferable cutter life.
Further, as shown in Figure 2,3, the rear corner surface 53 is gradually radially outer inclination since cutting edge inclination face 52
Tiltedly, the angle d of rear corner surface 53 and datum level X are 9-12 degree when with adjacent preceding 51 intersection of edged surface.Angle d makes under cutting
The clast come is directed to external chip discharging slot 40 as far as possible, reduces the amount of debris in inner hole 60.
Further, as shown in figure 5, the depth e of the external chip discharging slot 40 is between 0.3-1.0mm.
A kind of use citing of the cutting tool of hollow mold insert sticking to mould:
Knife handle 10 is connect with electric hand drill 70, starts electric hand drill 70, cutting edge 50 is directed at hollow mold insert 90, is first slowly existed
Hollow 90 building up by welding of mold insert goes out locating slot, then continue firmly by tightly being cut.Because die casting generallys use left and right
The horizontal design of die sinking, hollow mold insert 90 are generally also horizontal positioned, therefore the clast in inner hole 60 can be with during the cutting process
It is discharged to the outside from chip-removal hole 30, prevents the clast in inner hole 60 from influencing cutting.
After hollow mold insert 90 has been cut, cutting edge 50 is contacted with mold 80, since the material of mold 80 is harder, behaviour
Author can significantly feel the variation of cutting dynamics, so as to judge whether hollow mold insert 90 has cut off completely.Make again
Remaining clast is cleared up with tools such as air guns, completes the taking-up operation of hollow mold insert 90.
It will be apparent to those skilled in the art that can make various other according to the above description of the technical scheme and ideas
Corresponding change and deformation, and all these changes and deformation all should belong to the protection of the invention patent claim
Within the scope of.
